Contradiction Graphs Determine VC Dimension
Researchers have introduced a novel method using contradiction graphs to determine the VC dimension of binary concept classes. This approach establishes that the order-m contradiction graph, G_m(H), can ascertain if the VC dimension of H is at least m. The full sequence of these graphs, (G_m(H)) for m >= 1, precisely determines the exact VC dimension, resolving a long-standing question in the field. AI
